BOX-STRAP TIGI-I'IENER.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed October 21, 1915. Serial lfTo. 57,124.

Toall whom it may concern.

Be it known that I, CHARLES H. PETER- MANN, a citizen of the UnitedStates, anda resident of Natalbany, in the parish, of Tangipahoe andState of Louisiana, have invented a certain new and useful Improvementin Box-Strap Tighteners, of which the following is a specification.

The main object of my invention is to provide a tool of durable butsimple and inexpensive construction, by the use of which a box strap orsimilar device may be readily tightened by overlapping portions thereof.

A further object of my invention is to provide means within the tool forholding a nail or similar fastening device, which is adapted to bedriven through the overlapped portions of the strap.

With these and other objects in view which shall become apparent as thedescription proceeds, my invention resides in the construction,combination and arrangement of parts to be hereinafter described andclaimed and illustrated in the accompanying drawings forming a part ofthis specification, and in which like reference characters indicate likeparts.

Figure 1 is a perspective view of a box with my improved tightener inoperative position upon a strap. Fig. 2 is a similar view after the toolhas been turned to tighten the strap. Fig. 3 is a vertical section onthe line 83 of Fig. 2. Fig. 4 is a vertical section of a box strap andbox after the strap has been secured in its overlapped or tightenedposition. Fig. 5 is an enlarged View of the tool.

In the drawing A is a box of standard construction having the fasteningstraps B. My improved tool for tightening these straps consists of a bar1, having an end portion 2 cylindrical in cross section, and bent atright angles to the main portion of the bar which is used as a handle.Diametrical slots 3 and 4: at right angles to each other are out in theend of the cylindrical portion 2 as clearly shown in Fig. 5. The slot 3which lies in substantially the same plane as the handle portion 1 ofthe tool, is of a length and width adapted to receive a box strap, whilethe slot 4 is of suflicient width to receive a holding nail 5, and ofsuch a length that the base thereof will be over the center of the boxstrap which is inserted in the slot 3. By this arrangement the slot 4forms a convenient gage to insure the nail being driven through thecenter of the strap.

The operation of my tool is as follows. The strap B which it is desiredto tighten, 1s inserted in the slot 3 as shown in Fig. 1. The handle isthen grasped and the tool turned over to the position shown in Fig. 2,when the slot 4 will be substantially vertical and the strap will beoverlapped as clearly shown in Fig. 3 A nail is then placed in slot 4atthe base thereof, so that it will be above the center of the boxstrap, and is driven through the strap and into the box for a slightdistance. By a lateral movement thereof, the tool may now be removedfrom the strap, and the nail driven the remainder of the way into thebox as clearly shown in Fig. 4, thereby securely fastening theoverlapped portion of the strap to the box and so tightening the strapupon the oox.

It will thus be seen that I have provided a strap tightener of simpleconstruction by the use of which a box strap may be easily and quicklytightened and secured in its tightened position.

1. A strap tightener consisting of a handle bar and an arm at the endthereof and at right angles thereto, the extremity of the said arm beingprovided with longitudinal diametrical slots lying in planes at rightangles to each other, one of the said slots lying in substantially thesame plane as the handle bar and being of a width adapted to receive abox strap, and the other slot being adapted to receive a holding nailand of approximately one half the length of the first mentioned slotwhereby the base of the second slot will operate as a gage to center theholding nail between the edges of the strap to be secured.

2. Astrap tightener consisting of a handle bar and an arm at the endthereof and at right angles thereto, the extremity of the said arm beingprovided with means for engaging a box strap in such a manner that arevolution of the same will overlap portions of the strap, the said armbeing also adapted to receive a fastening device to be driven throughthe said overlapped portions.

3. A device of the character specified comprising a bar provided at itsextremity with longitudinal diametrical slots lying in planes at rightangles to each other, one of the said slots being of a width adapted toreceive a box strap, and the other slot being adapted to receive aholding nail and of approximately one half the length of the firstmentioned slot whereby the base of the second slot will operate as agage to center the holding nail between the edges of the strap to besecured.

4. A device of the character specified comprising a bar provided withmeans for engaging a box strap in such a manner that a Copies of thispatent may be obtained for revolution of the same Will overlap portionsof the strap, the said arm being also adapted to receive a fasteningdevice to be driven through the said overlapped portions.

5. A device of the character specified comprising a bar having slots inthe end thereof at right angles to each other, the said slots beingadapted to receive a box strap and a fastening nail respectively as andfor the purpose specified.
